Universality classes for the coalescent structure of heavy-tailed Galton–Watson trees
Universality classes for the coalescent structure of heavy-tailed Galton–Watson trees
Consider a population evolving as a critical continuous-time Galton–Watson (GW) tree. Conditional on the population surviving until a large time T, sample k individuals uniformly at random (without replacement) from amongst those alive at time T. What is the genealogy of this sample of individuals? In cases where the offspring …
